Telecommunications > Receiver Or Analog Modulated Signal Frequency Converter > Frequency Or Phase Modulation Frequency Or Phase ModulationFrequency Or Phase Modulation patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.02/22/07 - 20070042735 - System and method for generating optical return-to-zero signals with differential bi-phase shift and frequency chirp A system and method for generating an optical return-to-zero signal. The system includes an electro-optical conversion system. The electro-optical conversion system is configured to receive an input electrical non-return-to-zero signal, process information associated with the input electrical non-return-to-zero signal, and generate an output optical return-to-zero signal based on at least ... 01/11/07 - 20070010223 - Digital baseband receiver with dc discharge and gain control circuits A digital baseband (DBB) receiver for receiving and processing a wireless communication signal. The DBB receiver includes at least one low noise amplifier (LNA), at least one demodulator, a direct current (DC) discharge circuit and an LNA control circuit. The LNA selectively amplifies the communication signal. The demodulator outputs analog ... 04/20/06 - 20060084401 - Integrated structure of inductances with shared values on a semiconductor substrate An integrated circuit including a structure of inductances on a semiconductor substrate, intended for operating at frequencies greater than several hundreds of MHz, including a first inductance formed by a conductive track and having first and second terminals respectively connected to each of the two ends of the conductive track, ... 12/08/05 - 20050272388 - Safe traffic control system, method and apparatus The present invention demonstrates that light-emitting diodes (LEDs) have electrical characteristics that can be used to dramatically reduce the complexity and cost of the traffic signaling equipment needed to control the array of signals to give the right of way to the vehicles in a given intersection. This also enhances ... 10/13/05 - 20050227653 - Broadband radio transceiver with optical transform A broadband receiving apparatus includes an antenna to receive a radio signal having a plurality of modulation frequencies. An amplifier drives a laser source from the broadband radio signal to produce an optical signal having a plurality of spectral components. A diffraction grating transforms the optical signal into its spectral ... 09/01/05 - 20050191980 - Method and apparatus for complex cascade sigma-delta modulation and single-sideband analog-to-digital conversion A complex cascade sigma-delta modulator for analog-to-digital conversion applications. The modulator includes first and second sigma-delta modulator stages, combined with a complex digital noise cancellation circuit. In addition, analog-to-digital conversion of baseband signals using a complex sigma-delta modulator is also presented. ... ### FreshPatents.com Support |
